Science is rarely certain about anything, and certainly not about most links between environmental exposures and health effects in people. Nonetheless, the evidence showing links to health grows ever stronger as research progresses and becomes ever-more sophisticated:
- Scientists have generated compelling laboratory evidence revealing adverse effects in animals at low levels of exposure, affecting animal endpoints that are relevant to cancer, birth defects, reproductive effects, immune system dysfunctions, respiratory problems, learning and behavior problems, etc.
- They have demonstrated that many of the underlying mechanisms causing those effects in animals are similar, if not identical, to human mechanisms.
- They have documented human exposures to chemicals at levels that produce harm of many types in animals.
- And they have identified trends in human health and disability that can be predicted on the basis of the above.
But establishing scientific certainty of harm to people is elusive at best and in many cases likely to be impossible before countless people would be affected adversely. After all, epidemiology can only establish harm after an epidemic has occurred. Purposefully carrying out controlled experiments on people is considered, appropriately, unethical. And thus we are left with the plethora of uncontrolled, largely unmonitored experiments currently underway because of ubiquitous exposure.
Given these limitations, and given that our current regulatory system is unlikely to strengthen exposure standards absent much firmer proof, what is a person, or a parent, or a family, to do?
Much good, practical advice is available on the web and in print. Some of the best places to turn for practical advice are listed below. In addition to pointing toward these resources, on this page we will highlight a few old themes (“constants”) and then focus on new issues that are emerging from recent research and analysis.
One general point: As you make choices about products to buy, things to do, food to eat, places to go, bear in mind that government standards for regulating environmental threats to health are at best a bare minimum and at worst completely inadequate and health threatening. So what you choose to do should always at least live up to those standards.
This is because government regulations represent a compromise negotiated between advocates for public health and parties, usually companies or trade associations, with an economic interest in protecting their access to the market. The playing field in which the negotiation takes place is strongly biased in favor of the vested interests, who have succeeded over several decades of lobbying to put in place evidentiary standards for proof of harm that make it very difficult to prevent marketing of new products, or removal of old, even in the face of compelling evidence of plausible harm. Decades of experience reinforce that conclusion.
- Smoking harms adults, children and the developing fetus. It’s not just the irritation of the smoke itself, it’s also compounds added to the tobacco, the paper and the filter that make their way into your lungs and your bloodstream. Rules #1-3: don’t smoke; don’t inflict second-hand smoke on someone else; and don’t allow smokers to share their second-hand smoke with you or your family, especially your young children.
- The fetus is remarkably sensitive to alcohol. Avoid alcoholic beverages during pregnancy. Otherwise impacts can last a lifetime.
- Ozone damages developing lungs. While studies have shown for some time that ozone can trigger asthmatic attacks, the latest research even implicates ozone in the actual causation of asthma itself. When ozone levels rise and local governments issue air pollution warnings, pay attention. Some local newspapers carry regular ozone notices. They are worth reading and heeding.
- Pollutants in some fish can damage the fetus, undermining development of disease resistance and cognitive development. Heed fish advisories posted by public health agencies.

- Some plastics leach biologically-active materials into food with which they come into contact, particularly when heated. If you must use plastic, at least don’t microwave food in it.
